It is a velocity question

A particle of mass m = 10kg moves along a straight line under the action of force F = λ/x4 , where λ is some constant. A measurement shows that the particle passes the point x = 1m with...

I'm not sure how to approach this problem and I'd really appreciate any help! If a ball is thrown directly upward with a velocity of 36 ft/s, its height (in feet) after t seconds is given...

An airplane is flying at 200 m/s at an angle of 30o north of east. How fast is the plane flying North? An airplane is flying at 200 m/s at an angle of 30o north of east. How fast is the plane flying...

Joe decides to construct a new toy. He takes a solid fuel rocket engine from his model rocket kit and a flat bed rail car from his train set . He straps the engine to the back of the rail car. He...

Calculate the minimum change in velocity (delta V or ∆V) required for the Space Shuttle to decrease its altitude to 60 miles if it’s orbiting with an apogee of 236 miles and a perigee of 220 miles...

What is the momentum of a system of two particles with these respective masses and velocities: 3.75 kg moving north at 5.6m/s and 4.2 kg moving northwest at 2.3m/s?

A 42 kg child slides from the top of a 3 m high playground slide. With what speed will the child reach the bottom of the slide assuming: (a)There is no friction? (b) 23 J of energy is dissipated due...

Options are i) v=0 ii) v=2u iii) v=0.5u iv) v=u

A ball is thrown upward with an initial velocity of 42 meters per second from a cliff that is 10 meters high. The height of the ball is given by the quadratic equation h=-4.9t^2+ 42t+70 where...

answer

44/45= 0.97 how do I add the Miles per second and the direction (East)?

Find the deceleration in m/s/s from 40m/s to 0m/s in 8 seconds.

That is the exact question.

The velocity of a sky diver t seconds after jumping is given by v(t) = 80(1 − e−0.02t), measured in feet per second.

What was the maximum height and maximum range of the bullet? I got the answers of Δy=44.1 m And Δx= 60.0 m

(a) constant velocity problem (b) free fall problem

(a) increase (b) remain the same (c) decrease

Andy and Mina were having a race. They started at noon. Mina was running at 15km/h, while Andy was only one third of that speed. Once Mina was 500 meters apart, Andy sped up running 4 times the speed,...
